Belief Revision

Ask about this topic

Overview

Belief revision asks how an agent should respond to new information: accept it, adjust existing beliefs, or reject it while avoiding inconsistency. Formal approaches include AGM and Katsuno–Mendelzon postulates, plausibility orderings, and dynamic epistemic logic; newer systems also use explicit evidence records, dependency graphs, and uncertainty-aware update rules. In AI, these ideas guide language-model agents handling conflicting sources, persistent memory, user preferences, plans, and multi-turn dialogue, with evaluations on tasks such as conversational memory, navigation, and information seeking. A central tension is how to remain open to credible corrections without letting noisy evidence, social pressure, or one mistaken update destabilize useful beliefs and downstream actions.
